This invention relates to stop signs or road markers and an object of the invention is to provide a marker adapted for use in a roadway and one which will not injure vehicles when struck by them and which is practically indestructible.

A further objectis to provide a marker in which reflectors may be embedded, which,

marker will be substantially indestructible.

i vided a shell 10 preferably of pressed steel or other suitable material which shell is provided with a number of holes 11.. The shell is preferably made up of two hemispheres Welded together at 12 and in which a link 13 is welded to which a chain 14 is secured, the

other end of the chain being preferably,

secured in a block of concrete 15 embedded in the roadway 16. As shown the block 15 may have an enlarged lower end to insure its being securely held in the roadway. In order to permit the ball to swing about freely a swivel 19 is provided in the chain.

Within the shell 10 are provided hemispherical reflectors 17 These reflectors may 0 be of any suitably polished or other light reflecting material, such for example as red glass. The interior of the reflectors is filled with concrete or other suitable material 18 after which the shell or casing is welded together as'indicated at 12.

It will be readily seen that a marker built up of the material and in the manner indicated will provide a solid practically indestructible ball. The steel outer casing will Withstand the impact ofsuch vehicles as may Figure 1 is'a perspective view of the decollide with theball and this casing together with the concrete corewill insure that "the reflector casing 17 is uninjured by the trafiic which may collide with the-ball; By provid ing thechain 14 as ananchor the ball= is per-'-- mitted to swing aside when 'struck' by thewheelsbf vehicles, moreover 'theball will not injure vehiclesa Furthermore by providing a are necessarywinthe road and-consequently ball marker of this character no depressions I ll) A further object is to provide a markerthere will be no puddles of waterior mu'd such as are u'sually caused byJdepr'ession's in which stationary roadmarkers are fixed. 1 :Fu rther-Q more, due: tothefactthat the .ballm'ayswing about itjis kept clean by the rollingactionu Any. tendency. of 1 the pockets s in the ball to fill with water and freeze up is avoided'since the'swinging of the ballabout' its anchorage keeps thepocketsjempt'y and.the'ball free of mud.-

It will be obvious to those skilled in the art that various changes may be made in our de; vice without departing from the spirit of the invention and therefore we do not limit ourselves to what is shown in the drawings and concrete adapted to be embedded in a road bed, a ball, a chain anchored at one end in the block. and secured at the other end in a.

ball, said ball having light reflectors secured therein, substantially as set forth.

3. A road marker comprising a ball flexibly anchored on the surface of a road bed, said ball having a plurality of perforations, each perforation having light reflecting 'means therein, substantially as set forth.

4. In a street marker, a ball comprising a pair of hemispherical shells having openings spaced about their surfaces, a pair of light reflecting herispherical shells secured within T the first named shell, the interior of the reflecting shells being filled with concrete or other suitable material and the shells being Welded together, substantially as set forth.

5. In a street marker, a ball comprising a pair of hemispherical shells having openings spaced about their surfaces,\a pair of light reflecting hemispherical shells secured within the first named shell, the interior of the reflecting shells being filled with concrete or other suitable-material and the shells being Welded together, and a chain welded in the said shell said chain being adapted to be an chored in a road bed, substantially as set forth.

1 6. A streetvniarker comprising a ball having. apluralityof sockets in its periphery, said sockets havinglight reflecting IHGZLIISPO- sitioned therein,- and a chain attached to the' ball at. oneend andsecured in the roadbed at the other end, the chain having a swivel link therein to pennit'free rolling of the'ball about its anchor point, substantially as set forth..

7: A' streetlna-rker comprising a ball hav mg a chain secured thereto, said chaln being pivotally securedaat its other end to the surface "of a road bed, substantially as set forth.
